CountZero in 3 consecutive post uber rant shocker!!
The sinkhole in Louisiana, referenced in the video, is in fact the result of injection mining, which although not fracking, uses similar techniques.
Admittedly, the real cause of the Bayou Corne sinkhole is the salt caverns:
Evidence from drilling suggested that the sinkhole was caused by collapse of a side wall in a cavern in the Napoleonville Salt Dome.
This type of collapse from the side is “something regulators and briners had previously considered impossible—highlighting, once again, how poorly understood the geology of salt caverns truly is,”
Now, pardon my enquiring mind, but is it not then safe to assume that there may be other areas of the subterranean landscape that supposedly qualified parties do not hold full understanding of?
